X A B C D
P(X) .30 .20 ? 0.28

Find P(A and B) assuming that A and B are independent.

A. 0.1
B. 0.22
C. 0.5
D. 0.06

Answer 1

For independent events, P(A and B) = P(A) X P(B)

Answer 2

Which would give ....?

Answer 3

Would give what?

Answer 4

If you multiply the probability of A times the probability of B, what answer do you get?

Answer 5

Idk

Answer 6

P(A) = .30; P(B) = .20, so then .30 X .20 = .06
